Shock In standard tests, the relay has withstood 15 g in each of three
mutually perpendicular planes without structural damage or
degradation of performance.
Vibration
In standard tests, the relay has withstood 2 g in each of three
mutually perpendicular planes, swept over the range of 10 to 500 Hz
for a total of six sweeps, 15 minutes each sweep, without structural
damage or degradation of performance.
Isolation
